As the leading enterprise email platform, Microsoft 365 is natively and comprehensively integrated with WiseSignly. You can deploy server-side SMTP relay for seamless, invisible signature injection on outbound mail, or use the Outlook Add-in to display compose-time signatures driven by rich context rules. Both deployment modes connect securely using Microsoft admin consent and automated directory synchronization.
